l with the object of compactly arranging the parts and alsoso arranglng, constructing, and grouping the parts that the device is fully and lequally operative when the parts are placed vertically with the signatures or sheets hori- Zontal or when the parts are placed horizontal with the signatures or sheets vertical.

My improved machine comprises a platform supporting the group or groups of signatures or sheets to be stapled and preferably a conveyer for progressively moving the same along, Standards secured to and rising from this platform support a bar carrying thereels.

of wire for the staples and also serve as guides for a vertically-movable feed-bar for moving the Wire forward and for a resser-bar adapted to bear upon the group o signatures or sheets at the time the staples are applied. This presser-bar carries swinging yielding dieblocks positively held for the moment that the wire is cut and one end is overturned to form the staples, and which die-blocks when released are moved downvand swing with the downward movement of the parts to force the staples through the group of signatures or sheets. The cutters and said holding devices are actuated by rocker-arms and facecams on a revoluble power-shaft. A crank on this shaft and connecting-rod and a crossbar connected thereto effect the vertical movement of rods which in turn cause or permit the movement of the feed-bar and presser-bar and also a cross-head and plungers attached thereto, all of which are hereinafter more particularly described.

The conveyer hereinbefore referred to is the conveyer of a signature and sheet gathering machine, from which the piles lof signatures or sheets are progressively delivered to the sta ling-machine to be bound as collated. In t edrawings, Figure 1"is an elevation and partial section representing my improved machine. Fig. 2 is a side elevation and section on the dotted line of Fig. 1,

and Fig. 3 is a sectional plan at the line y y of Fifi. 1.

krlhe platform a is suitably supported. It is provided with a rib etl at a sllght distance from the edge at the left hand of Fig. 2. The

a2, extending downwardfrom the underside of the platform. There are in the platform o enings 2,in which dogs 3 are pivoted, and t e platform is `provided vwith a chain-conveyer device 4, having posts 5 at intervals and extending from a signature and sheet gathering machine, and b represents a pile of signatures or sheets upon the platform a and against one edge of which the post 5 rests, the conveyer and post, as shown in Figs. 2 and 3, being in the act of moving the pile of signatures or sheets along upon the platform. It will be noticed that the rib a along one edge forms a guide for the ile of signatures or sheets and also a means o keeping them true in relation to one another.

c d are standards having flanged lower ends that rest upon the platform and threaded portions passing through the platform and nuts 6 on the lower endsl to secure the standards in place. These standards are rovided with pins 7 vand collars 8 and below the collars 8 there are springs c d. The upper ends of` the standards c d are exteriorly threaded, and a bar e extends acrossbetween and is connected to and supported by the standards c d, the same being secured in place to the standards by the nuts 10. The bar e has upward extensions or bracketarms e', with pins 11, which form the axes for the reels c2 of wire, from which the staples are made.

Upon the back of the bar e there are series of guiding and straightening rollers ff, bef

tween which the wire as it comes off the reel passes, and below these groups of guide and straightening rollers are pairs of dogs 12 13, which bear at one side upon the wire, there being lugs on the bar e (shown-in Fig. 1 by dotted lines) at the other side of the wire. The dogs are preferably spring-actuated, so as to be kept up against the'wire, and they serve the purpose of holding the wire in position to prevent any upward movement of the v6o platform is also provided with guide-sleeves IOC wire with an upward movement of other parts of the machine.

A feed-bar g extends across the machine. Itis perforated for and slides upon the standards c d. This feed-bar is also provided with .lugs on the back and with spring-actuated groups of dogs 14 15, the wire from the reels passing through between the lugs and the dogs. The upward position of the feed-bar g is determined and limited by the nuts 9 upon the standards c d, which nuts may be moved along the threaded parts of the standards to eiect the desired adjustability.

f h is a presser-bar with extensions h at its ends, which are perforated for the standards versely slotted and provided with lugs 16 in pairs, to and between which are pivoted the die-blocks i fi. The shape of these die-blocks will be apparent, especiall from-Fig. 2. The under surface is semicircu ar, and the surface thereof in position agrees substantially with one direction.

the base of the of each die-bloc resser-bar h. The back end is heavier than the forward end, which is ta ering in the form of a hook, and the upper e ge of the forward part is flat.

The presser-bar h is perforated or apertured from opposite ends, the upper aperture at each-end receiving the cutter-bars 7c and the lower apertures at the respective ends the locking-bars Z. The portion, Fig. 1, in section shows the relation of the locking-bar Z and the cutter-bar 7c to the presser-bar h and the die-block i, in the extreme movement in Eachl locking bar passes through a hole in its coacting die-block a little in advance of the end of the cutter-bar, so that the die-block is held in position. Each cutter-bar k at its outer end is turned at a right angle and provided with a pin c, and the upperends of the locking-bars are bent up at a right angle and pass through' openings in the cutter-bars to connect the cutterv bars and locking-bars together.

I rovide rocker-arms m m', pivoted at 17 to t e platform a, which at their lower ends are provided with rollers and at their upper ends are forked to receive the pin ends k of I have shown and may prefer to employ springs 18 between the guidesleeves a2 and the rocker-arms fm m for eHecting the return movement of the rocker-arms.

.6 5 cam n3, which in part performs the office of the othercrank-arm, there being a crank-pin between the crank-arm and the cam to which the connecting-rod 19 is fastened. The crossbar 2() is provided with heads-21 at its ends,

and to this cross-bar the oppositeend of the rod 19 is connected. The rotation of the power-shaft n, the crank-arm n2, and cam n3 with the movement of the rod 19 serves to raise and lower the cross-bar 20 and its heads 21. I provide vertical rods o o at their lower ends secured in the heads 21. yThese rods pass through the guide-sleeves a2 of theplatform. They pass on up through the opposite ends of the presser-bar h through openings in the feed-bar g and the bar e, the openings in the bar e being guides for the upper ends of these rods. Upon these rods 0 o are collars 27, inned thereto between the feedbar g and t e bar e. The rods o o also pass through the cross-head 1', which is pinned thereto, and between the cross-head r and the feed-bar g, around the rods o o', are springs 26. The cross-head r carries the Aplun ers r', which are secured thereto and whic pass down through vertical apertures in the presser-bar h, which apertures intersect the openings for the cutter-bars 7c and locking-bars l and are directly in line with the positions of the die-blocks i 'L'. Pins 24 pass through the rods 0 o and through slots 25 in the opposite ends of the presser-bar h from the lower edges of said bar up to said pins. I further provide a T-head 23 with a' rounded lower end adapted to rest u on the upper surface of the cam n3, and w 'ch T- headis held in position and guided by a pin 22, depending from the under surface of the latform a, The wires to form the staples fiom the reels e2 pass down between the series of guiding and straightening rollers ff, between the lugs of the bar e and the pairs of do s 12 13, between the lugs of the feed-bar g an the series of dogs 14 15, back of the crosshead r, and through openings provided therefor in the presser-bar h immediatel alongside of the openings'provided for tffe plungers r.

The operation of thedevice is substantially as follows: The parts shown in Fig. 1 are in the relation Which they will assume when a pile of signatures or sheets has been brought along by the conveyer device 4 to a predetermined position on the platform and the cams n have moved the rocker-arms m m, forcing the locking-bars Z and cutter-bars 7c into the presser-bar h to first lock the dieblocks i i in position and then to cut off theI wire and bend the upper ends of the wire, Which agree with the vertical thickness of the cutter-bars, over upon the upper surfaces of the die-blocks i OY, so as to form the rst bend of the staples. In this positionit will be noticed that the crank-pin of the crankarm n2 and cam n3 is at its highest point. (See especially Fig. 2.) As the same moves down IOO IIO

izo

the cross-bar 20, the rods o o and the pins 24 move downward. The quick-acting cams 'n n change position, so that the springs 18 or equivalent devices act arms m m to withdraw the cutter-bars 7c and locking-bars Zfrom their active position and release the die-blocks i i. As this movement takes place the presser-bar h'lowers both by gravity and by the expansive action of the springs c d the cross-head 1" and plunger r follow down with the presser-bar, and the collars 27 move down to contact with the upper surface of the feed-bar g. At this moment the presser-bar is in forcible contact with the pile of sheets or signatures to hold the same in position. The further downward movement of the rods o o by the action of the connecting-rod 19 and the cam device brings the lower ends of the plungers r into contact with the bent end of the staple upon the upper surface of the forward portions of the die-block and moves the feed-bar g in proportion because of the collars 27 resting thereon. This downward movement advances the wire for the next staples, because the function of the dogs 14 15 is to so hold the wire that the feed of the same is bound to take place. This downward movement continues the pressure exerted by the plungers r upon the staples and the upper surfaces of the die-blocks, gradually swingingA the dieblocks upon their pivotal connection with the lugs 16 the same moving out of the way as the parts and the staples move down. The fact that the presser-bar bears with force upon the signatures or sheets compels the end of the wires forming the staples in their grooves to be pushed through the signatures or sheets with the progressive movement of the parts until the bent ends of the wires rest upon the upper surface of the Apile of signatures or sheets, the downward movement at this time having been entirely completed, with the lower ends of the wires forming the staples projecting from the under surface of the signatures or sheets. With the upward movement of the bars o o, returning the parts to their initial position, the various series or groups of dogs slip'past the wire to engage a new portion, the plungers rise out of the way, the cams n act upon the rocker-arms m m to force the locking-bars Z and cutter-bars k to- Ward the position shown in Fig. 1, in which the die-blocks are held and the Wire cut of for the next staples, and the ends turned over upon the upper surfaces of the die-blocks. Simultaneous with this movement the cam n3 in its rotation and. in fact, substantially coincident with the extreme downward movement of the p arts, the pointed end of the cam acts'upon the under sideof the T- head 23 to raise the same toward and against the under surface of the platform a, swinging the dogs 3, pivoted in the openings 2, .upward, These dogs are so placed that the proupon the rockerjecting wires of the staples are right in line with the dogs and, in fact, are slightly bent by the dogs as they pass through the pile of signatures or sheets, and this upward movement with force bends the lower portions of the wires against the under surfaces of the signatures or sheets to complete the form of the staple and to hold the signatures or sheets between the opposite bent ends thereof. These operations are thereafter progressively repeated with new piles of signatures or sheets. The special office performed by the nuts 9 in their adjustable character is to permit the feed-bar gto move farther along the rods o o', so that the groups of dogs 14 15 connected thereto can engage the wires farther along in their length, so that with each movement a greater length of wire is taken up for a longer staple in proportion to the thickness of the pile of superimposed signatures or sheets going to make up the small book or pamphlet. The springs 26 between the cross-head r and feed-bar g keep these parts separated and are sufficient to raise the bar g to contactwith the nuts 9 wherever they may be placed. They, however, will yield for the extreme movement of the several parts with relation to one another, so that the full movement of the cam device through the rods o o may be impartep to the feed-bar g and the wires for the lengths of the staples desired.
